My INR's have always been unstable. But recently they are very strange. Since February I was placed on a new medication that interferes with warfarin but the last few months the medication has been reduced, warfarin increased and my INR has dropped from 2.1 to 1.2. I was on 10 mg of Warfarin and I'm now on 13mg with the plan to go up to 14mg on Monday. All my health providers as well as myself are very confused. Any ideas why my INR continues to fall?
